EXPERIMENT DATA FOR TWO SHIPS OF 'MINIMUM' RESISTANCE,
Abstract
This report presents the results of towing-tank tests carried out on two of the models of minimum 'total' resistance described in an earlier report by Lin, Webster and Wehausen (1963) (AD-417 630). One model was symmetric fore and aft, the other asymmetric with a prescribed afterbody. Each was supposed to be optimum within its class for a Froude number 0.316 and a Reynolds number 1.18 x 10 to the 9th power. Although the forms showed resistance qualities near the design speed as good as the equivalent forms for Taylor's Standard Series, they were not significantly better. The occurrence of separation behind the stern bulb of the symmetric model may have masked possible superior wave-making qualities as indicated by a rather small surface disturbance. (Author)
